LUBRIQATOR.

SPECIFICATION forming part of Letters Patent No. 760,876, dated. May 24, 1904.

Application filed March 17,1903.

T0 at whom it may concern: I

Be it known that I, HENRY L. KINCH, a citizen of the United States, residing at'Salina, in the county of'Saline, Stateof Kan'sas,have invented certain new and useful Improvements in Lubricators; and; do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable oth'- ers skilled in the art towhich it appertains to make and use the same. 7

This invention relates to lubricators ffor steam-engines, and has for its object to provide a deviceof this nature which will be automatically regulated to admit different amounts, of the oil to the cylinders and which will utilize the exhaust-steam from the engine to accomplishthis object.

Other objects. and advantages of the invention will be understood from thefollowing description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similarparts in the several views, Figure 1 is a side elevation of the device. Fig. 2 is a central longitudinal section showing the device' in operation under low exhaust-pressure and with the reservoir partially empty. Fig. 3 is aview similar to Fig. 2, showing the device'in its inoperative position with the exhaust-valve closed and with the follower-engaging catch in its operative position. Fig. 4: is an end view of the reservoir, showing the catches 15; and Fig. 5 is a detail view of the bell-crank lever.

. Referring now to the drawings, the present device comprises a reservoir 5 for the reception of lubricant having a filling-opening 6, provided with a screw-cap 6', an air-inlet 7 and a drain-cock 8. Disposed within the reservoir is a follower 9, attached to a plunger 10, passing through an opening 11 in a screwcap 5', disposed upon one end of the'reservoir. The opening 11 is threaded and is provided with a bushing 12, having a flange 12 on either end thereof, said bushing being adjustable into and out of the reservoir to vary the tension of a spring 13 disposed about the plunger between the inner flange 12 and the follower 9. The plunger 10 has a reduced portion 14: adjacent to its inner end and re- Serial No. 148,243, a. model.)

,sulting in shoulders 14;. Attached to outer flange 12 of the bushing 12 are a pair of slid-, ing catches 15, whichmay be engaged with; the shoulders 14; when the plunger 10 is at the limit ofits outwardmotion to prevent its freturn. In the opposite end 5" of the reser-v voir is an outlet-opening 16, having an elbow .17 connected therewith, said elbow being.- -pro'vided'with an ordinary form of stuffingbox to receive the sight-glass 18, the upper end of which'is disposed in a second stufling-f ;box 18, from which a connection'lea'ds to the icylinders of the engine. The elbow 17 also contains the seat 19 of a needle-valve, the needle 20 of which enters through the bottom of the elbow. This needle 20 is adjustablein acollar 21, pivoted between the jaws 22 of a ib'ell-erank lever 23, journaled in a bracket 24;. .upon the bottom of the reservoir.

Thebellcrank lever 23 has a perforation therethrough at a point between the needle-valve and the bracket 24. through which, freely passes a threaded rod 25, the upper end of which is attached to the elbow 17 Disposed between the lever 23 and a thumb-nut 26, engaged withv the threads of the'rod 25, is a spring 27, whichnormally holds the lever 23 raised andthe needle 20 in engagement with the seat 19, to

close the valve and to prevent the egressof the oilfrom the reservoir.

,Attached to one side of the reservoir 5 means of brackets 28 and 29 is a cylinder 30,

having apiston 31disposed therein, which, piston is attached to the end of a piston-rod 32, the outer end of which is pivotally con- ;nected with one end of the bell-crank lever 23. The cylinder 30'has an opening 33 in the side thereof, with which is engaged an excap 6. The catches are then disengaged from the shoulders 14:, and the pressure eX- erted by the spring 13 is put upon the oil, which is prevented from leaving the reservoir by the needle 20, which is held in engagement with the seat 19 by the spring 27. Should the engine now be started, the exhaust-steam from the cylinders passing through the pipe 34 would enter the cylinder 30 and would cause suflicient pressure to move the piston 31 therein. This movement of the piston 31, through the medium of the piston-rod 32, is communicated to the lever 28, which is moved against the action of the spring 27, moving the needle 20 from the seat 19 and permitting the egress of aquantity of oil from the reservoir which will pass upwardly through the sight-glass 18 to the. cylinders of the engine. It will of course be understood that under certain cond itionssay when the engine is exerting its greatest amount of powerthe pressure in the cylinder will be greater than at other times, which will act to move the piston 31 a greater distance and admit a larger supply of oil to the cylinders. When the engine is stopped, the pressure in the cylinder 30 will of course be removed, and the valve will be closed through the action of the spring 27.

In practice modifications of the specific constructionshown may be made, and any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

What is claimed is 1. A lubricator for engine-cylinders com prising a reservoir for the reception ofthe lubrieant,said reservoir having an inlet-port and an outlet-port, a closure for the inlet-port, a valve for the outlet-port, a pipe connecting the outlet-port with the cylinder of the engine, means for forcingthe lubricant from the reservoir, a cylinder having a larger and smaller opening therein, a piston disposed within the cylinder, connections between the piston and the valve of the outlet-port for operation of thelatter by movement of the former and a pipe connection between the larger opening of the cylinder and the exhaust-port of the engine to admit steam to said cylinder for movement of the piston.

2. A lubricator for engine-cylinders comprising a reservoir for the reception of a lubricant, said reservoir having an inlet-port and outlet-port, a closure for the inlet-port, a inbricant-conducting pipe attached to the outlet-port connecting with the cylinder of an engine, means for forcing the lubricant from the reservoir, a valve in said pipe, a valve-actuating cylinder having a larger and smaller opening therein, said larger opening being connected with the exhaustport of the engine fo r the'admission of the steam tosaid aetuatingcylinder, a piston disposed within said cylinder, to be operated by the steam, a rod attached to the piston and passing out of the cylinder through an opening in the end thereof, aconnection between the end of the rod and the valve of the elbow for operation of the latter by movement of the former, and means for holding the valve normally closed.

3. A lubricator for engine-cylinders comprising a reservoir for the reception of a lubricant, said reservoir having an inlet-port and an outlet-port, a closure for the inlet-port, an elbow attached to the outlet-port and having an opening therethrough for the passage of thelubricant, a pipe connecting the elbow with the cylinder of an engine, a valve in the elbow to close the passage, means for holding the valve normally closed, means for forcing the lubricant from the reservoir, a cylinder having a larger and smaller opening therein, said larger opening having a pipe connection with the exhaust-port of the engine, a piston disposed within the cylinder to be operated by the exhaust-steam from the engine and connection between the piston and valve to operate the latter against the action of the closing means.

In testimony whereof I afiix my signature in presence of two witnesses.

HENRY L. KINGH.
